The way I line up things is to create a background image of the airport using www.historicaerials.com/
1. Search for Nashville airport. You may end up a little northeast of the airport, zoom out with the mouse wheel and drag the mouse around until you find the airport.
2. Click on Aerial. There are two choices, 1951 and 1957, choose whichever is closer to your desired year (i.e. closer to the correct layout for that year).
3. Zoom in (mouse wheel) until the numbers in the lower left corner say 50m/300ft.
4. Scroll on the right until the entire window is on screen. Move (drag with the mouse) until one corner of the airport is visible on the screen.
5. Use Alt-Prt Scr to capture the window.
6. Paste into your favorite paint program.
7. Back at historic aerials, move the image so a new part of the airport is visible (let there be some overlap from the previous image in step 5). DO NOT zoom in or out, keep the zoom constant.
8. Repeat 5 through 7 until you have covered the entire airport. I do this in a logical progression (i.e. along the bottom edge from right to left, then up one and then across again from left to right, etc.). This creates a serpentine pattern of captures.
9. Now in your paint program, start with the image of the top and left edge of the airport and increase its Canvas Size (i.e. add extra area to the image) so it's around 4000 x 4000 pixels. The original image should remain at the top left, of course. Cut and Paste it there if needed.
10. Now choose and copy the next image that is just to the right of the original image and paste it into our large bitmap. Slide it around until it lines up exactly (to the pixel) with the original image there. The overlap should help here. The HISTORICAERIALS.COM and COPYRIGHTED MATERIAL words on the images should help you line these up.
11. Repeat step 10 until the entire airport has been placed into the large image. You can delete the original small images once you use them (if you are SURE you don't need them anymore). If you need more room, increase the Canvas Size again.
12. If you end up with some holes in the image, go back to the web site and take images of those areas, and paste them into the holes.
13. Once this is complete, Crop away any extra blank background that is unused (keeps the pixel size down).
14. Save this image with the code of the airport and the date (i.e. KBNA_57.jpg). I save it to the ADE/FS9/Images folder.
15. Now in ADE, right click the center of your airport and choose Add.../Image.
16. Click the ... button and find where you saved your image. Click it and click the Save button. The image should appear under your airport.
17. I have been lucky and the main runway in the modern airport has always been present in the classic version. If so, drag the background image so the runway image lines up with the ADE runway (it is often shorter, though). Look for old taxiways, etc. that still remain so you can line them up too.
18. Note that it will not be the correct size. Once you have determined the length of the main runway (see NOTE below) and edit the ADE runway to that length (and position it properly), the next step is to match the runway lengths (image vs ADE runways).
NOTE: The way to determine the runway's length is right from the historicaerials.com image. Click on the Measure button, then on Creat a New Measurement, and click at one end of the runway. Then move the mouse to the other end of the runway, click, and read the distance on the screen. You can click again to extend the distance to that point. When done click the Cancel button. If you double click the mouse, the line becomes permanent and I don't know of a way to remove it! I just cancel. We also use this technique to figure out the dimensions of any buildings we need to build in GMAX, Sketchup, etc.
Note too that if the runway is actually a different length than in the image (i.e. let's say you are modeling 1960 and it had been lengthened between 1957 and 1960) you would first set the ADE runway to the image's length as described above, adjust the location and size of the image's runway (as in the steps below), and finally increase the length of the runway to its proper value in ADE. You can get runway length data from old Jeppesens or for international airports from flightglobal.
19. If you right click on the background image and choose Edit Object, click the box that says Preserve Aspect Ratio (and make sure it's checked every time you use this box).
20. Now change the value in the Width box until the image's runway length matches the ADE runway. You can drag the image around until it matches the correct location.
21. Finally, right click the image and choose Lock Object. This will keep it from being moved inadvertently.
Now you have a template to move everything into place. In addition, you can use this template as a guide to placing your buildings and other airport objects accurately.
Hope this helps,

Hope this helps,
are just to nullify the numbers which are in two different notations, that way you can still use the txt file as a calibration file with SBuilder9.
